Abstract
(Graph Presented) Photons control number of mobile charge carriers: Organic field-effect transistors based on dithiophene-tetrathiafulvalene (DT-TTF) and dibenzo-tetrathiafulvalene (DB-TTF) show enhanced conductivity under illumination (see figure). A very high ratio of photocurrent to dark current of the order of ≈ 104 was observed for DT-TTF due to the photogeneration of mobile charge carriers (holes). These materials have the potential to be employed as light sensors or optoelectronic memory devices.
